Probable dud app to the potential end user ... but consider how many permissions did the potential end users 'sign-off' on, and the peoples who are the underwriters of the app ... they just gained a lot of personal data they see via the device it was loaded on and any it is linked to . . . . imho

Just checked and my Box works fine on my Playbook, although I rarely use it. I am using an older version of Box (1.8.1.1) but it seems to work well. I just uploaded a few pictures and documents no problem.
